Add full decode pipeline for 0x2C partial records from the device's event
list, representing continuous monitoring intervals where no threshold was
crossed. These records appear interleaved with full triggered events in the
browse walk and were previously ignored.
minimateplus/models.py
- Add MonitorLogEntry dataclass: key, start_time, stop_time, serial,
geo_threshold_ips, raw_header, duration_seconds property
minimateplus/protocol.py
- read_waveform_header() now returns (data_rsp.data, length) — full payload
including the record-type byte at position 0 — instead of the sliced header.
Callers that need the old slice use raw_data[11:11+length] as before.
minimateplus/client.py
- Add _decode_0a_partial_header(): auto-detects 9-byte (sub_code=0x10) vs
10-byte (sub_code=0x03) timestamp format, handles 1-byte inter-timestamp
gap, extracts serial via BE anchor and geo threshold via Geo: anchor.
- Add get_monitor_log_entries(skip_keys=None): browse walk (1E → 0A → 1F),
decodes partial records, skips full records and already-seen keys.
minimateplus/__init__.py
- Export MonitorLogEntry
bridges/ach_server.py
- After get_events(), call get_monitor_log_entries(skip_keys=seen_keys) and
save new entries to monitor_log.json in the session directory.
- Add _monitor_log_entry_to_dict() helper.
- Include monitor log keys in downloaded_keys for state persistence.
CLAUDE.md / CHANGELOG.md
- Document 0x2C partial record layout (timestamp format, ASCII metadata
region, 1-byte gap edge case) confirmed from 4-11-26 MITM capture.
- Version bump to v0.10.0; update What's next.

CHANGELOG.md:
- New v0.9.0 section covering erase-all protocol, browse helpers,
delete_all_events(), ach_mitm.py, and ACH server overhaul
- Back-filled v0.8.0 section (write pipeline, monitoring, ACH server)
that was missing from the previous release notes
CLAUDE.md:
- Bump version to v0.9.0
- Add erase-all protocol section with full wire sequence, SUB 0x06
storage range response layout, and post-erase key counter reset notes
- Document ACH server state format (ach_state.json v0.9.0 schema with
downloaded_keys + max_downloaded_key)
- Add RV55 DCD/DTR issue to What's next

ach_server.py:
- Add ach_state.json per-unit state tracking (keyed by serial number)
- count_events() before any download; skip session if no new events since last call-home
- Download only events beyond the previous high-water mark (all_events[last_count:])
- --max-events N safety cap for first-run units with many stored events
- state_path and max_events wired through AchSession constructor and serve()
client.py (_decode_monitor_status):
- Revert monitoring flag to section[1] == 0x10 (was incorrectly changed to section[6])
- Fix battery/memory offsets to section[-10:-8], [-8:-4], [-4:] (no trailing checksum byte)
- Both confirmed by full byte diff of all 144 0xE3 data frames in 4-8-26/2ndtry capture
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
section[6] is the monitoring flag (was wrongly section[1] — section[1] is always
0x00 in both states). Battery and memory fields use relative-from-end offsets
(section[-11:-9], section[-9:-5], section[-5:-1]) instead of absolute positions,
which broke when the payload grew by 3 bytes in monitoring mode.
Confirmed from full byte diff of 142 0xE3 frames in 4-8-26/2ndtry capture.
SFM start_monitoring now polls /device/monitor/status every 5s for up to 60s
instead of a fixed 25s delay (unit runs ~40s on-device sensor check before
confirming monitoring state).
Also corrects stale 1C→6E response anomaly claim in protocol reference — no
exceptions to the 0xFF−SUB rule are known.
- Introduced new SUBs for monitoring status, start, and stop commands in protocol.py.
- Implemented read_monitor_status, start_monitoring, and stop_monitoring methods in MiniMateProtocol class.
- Added new API endpoints for monitoring status retrieval and control in server.py.
- Enhanced the web application with a monitoring panel, including battery and memory status display.
- Created a new Python script to parse SUB 0x1C response frames for monitoring status.
- Documented the monitoring status response format and field locations in markdown and text files.
Adds §7.8.4 to protocol reference and corresponding CLAUDE.md sections:
- End-of-stream: device sends exactly 1 raw byte after last chunk; handled
via TimeoutError + bytes_fed>0 check → graceful break to termination
- Chunk timing: ~1s per chunk, 35 chunks for a 9,306-sample event, safe
timeout is 10s (not default 120s)
- fi==9 decoder bug: hardcoded skip drops ~133 sample-sets per event;
noted as known issue pending fix
- ADC conversion: counts × (range/32767) → physical units (in/s for geo)
Changelog entries added for all four items (2026-04-06).
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- Added `_decode_a5_waveform()` to parse SUB 5A frames into per-channel time-series data.
- Introduced `download_waveform(event)` method in `MiniMateClient` to fetch full waveform data.
- Updated `Event` model to include new fields: `total_samples`, `pretrig_samples`, `rectime_seconds`, and `_waveform_key`.
- Enhanced documentation in `CHANGELOG.md` and `instantel_protocol_reference.md` to reflect new features and confirmed protocol details.
